Percocet and Lortab are opoid anagelsics, and according to by textbook (Keltner & Mosby's Nursing Drug Reference) they can be detected anywhere from 1 - 7 days in the urine and blood.

One must also take into account length of usage, how often used, body size and weight among a few other things.

I did not find the link above to be particularly helpful in that it stated that that with THC/marijuana (habitual use), for instance, is out of the blood in 24 hours, this information is incorrect. It takes Marijuana up to 15 weeks not to be detected in the blood. This is from pate 496 of Psychiatric Nursing, Fifth Edition, Keltler. The link is one specifically designed to sell "dextox" products.

Yeah, that is what I thought too, but in our substance abuse lecture they state that none of these products actually work anyway.

The link says something about the drugs being in the hair for only 90 days, that is only if you shave your head! LOL

Drugs can stay in hair follicles for much much longer than that. 90 days is 12 weeks, 3 months, THC can be detected in the blood for up to 15 weeks which is 3 weeks longer than what the site says it stays in the hair.

I see your point, however, there is nothing out there that will "erase" drugs from the hair follicle. So, traces may be smaller past the 3cm point, but they are still detectable. Closer to the 3cm point they are in much higher concentration.

My furnace burner does not stay long. I had my pilot light goes out. I lit the pilot light and it works. And as soon as I put the wall thermostat on ON position for heat, I can see the burner starts with the normal flame. But after 30 seconds burner flame goes off as well the pilot light goes out...

What period must I allow my tenants to 'stay' in my residence after being served with an eviction notice for non-payment of rent? Is the time frame the same throughout the State of Texas or does it vary by county?
